ter which it affords be compared with that of any of those 
species which flower nearly at the same time, it will be 
found greatly superior. It sends forth but a small number 
of flower-stalks, which are of a slender structure compared 
to the size of the leaves. This will account in a great 
measure for the equal quantities of nutritive matter afforded 
by the grass at the time of flowering, and the latter-math.

The produce of this grass is greater than its appearance 
would denote ; the leaves seldom attain to more than four 
or five inches in length, and the flower-stalks seldom arise 
to more. Its growth is not rapid after being cropped, nor 
does it seem to withstand the effects of frost, which, if it 
happen to be severe and early in the spring, checks it so 
much as to prevent it from flowering for that season; 
otherwise the quantity of nutritive matter which the grass 
affords (for the straws are very inconsiderable,) would rank 
it as a valuable grass for permanent pasture.
